The `platform` field is pointless nesting: it's just stuff that happens to be defined together, and that should be an implementation detail. This instead makes `linux-kernel` and `gcc` top level fields in platform configs. They join `rustc` there [all are optional], which was put there and not in `platform` in anticipation of a change like this. `linux-kernel.arch` in particular also becomes `linuxArch`, to match the other `*Arch`es. The next step after is this to combine the *specific* machines from `lib.systems.platforms` with `lib.systems.examples`, keeping just the "multiplatform" ones for defaulting.
